To aZZ whom, it may concern:

Be it known that l, JOSHUA HOLDSWORTH, a citizen of the United States, residing at Centerdale, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in finding-Machines, of which the following is a specification.

This invention has reference to an improvement in winding-machines, and more particularly to an improvement in jack-spool-filling machines.

In the process of preparing warp-threads for the warp-beam of a loom the threads are wound on a jack-spool from a creel and from a plurality of jack-spools onto the warp-beam of a loom. In winding the threads on the jack-spool from the creel each thread is reciprocated so as to occupy a space of three-quarters of an inch on the jackspool-that is to say, a jack-spool thirty-nine inches long between ends will hold fifty-two threads. In winding the threads on the jack-spool from the creel a thread is liable to break or an imperfect thread may be wound on the spool. In the breaking of a thread it has heretofore been the practice to tie thebroken thread, break all the other threads, wind the first thread to a level with the adjacent threads, tie all the broken threads, and then proceed with the winding of all the threads. This method of overcoming the difficulty is slow and detrimental in the Weave, as the ties or.

knots of the broken threads all come together on the jack-spool. This method is also used in the replacing of an imperfect thread with a perfect thread.

The object of my invention is to give a more perfect winding to the Warp-threads on a jackspool than has heretofore been done, and I accomplish this object by the use of my improved jack-spool-filling machine, whereby a cavity in the threads on the jack-spool caused by the breaking of a thread or the removal of an imperfect thread is filled without the breaking of all the threads.

My invention consists in the peculiar and novel construction of a jack-spool-filling machine adapted to fill a cavity in the threads on a filled jack-spool caused by the breaking of a thread or the removal of an imperfect thread, said machine consisting of a frame, front, back, and end rails forming a part of the frame, cross-struts adjustably secured to the front and back rails, bearings adjustably secured to the cross-struts adapted to hold a jack-spool, a supporting-frame adjustably secured to the front rail, bearings in the supporting-frame adapted to hold a driving-pulley and a spindle, means for revolving the driving-pulley, means on the spindle for holding a spool, a belt connecting the driving-pulley with a pulley on the spindle, a two-part circular frame the upper half of which is rigidly secured to the supporting-frame, a twopart ring-pulley, means for rotatably securing the two-part ring-pulley in the two-part circular frame, means for opening the twopart circular frame and ring-pulley to receive a jack-spool, a belt connecting the drivingpulley with the ring-pulley, a pin on the twopart ring-pulley adapted to hold aspool of warp-thread, a tension device on the ring-pulley, a reciprocating thread-guide on the ringpulley, and other details of construction, whereby the spool of Warp-thread on the ringpulley is revolved around the stationary jackspool and through the reciprocating threadguide fills the cavity in the thread on the jackspool with thread from the spool on the ringpulley, as will be more fully set forth hereinafter.

Figure 1 is a top plan view of my improved jack-spool-filling machine, showing the means for supporting the jack-spool in the machine, the two-part circular frame and ring-pulley surrounding the jack-spool, and the spool of warp-thread on the ring-pulley in a position to fill a cavity in the threads on the Warpbeam, said threads and cavity being indicated in broken lines. Fig. 2 is a vertical view of the machine looking at the front, showing the means for adjustably securing the cross-struts and the supporting-frame to the front rail of the machine. Fig. 3 is an enlarged detail transverse sectional view taken on line W W of Fig. 2, showing the supporting-frame adjustably secured to the front rail, the upper half of the two-part circular frame rigidly secured to the supporting-frame, the twopart ring pulley in the two part circular frame in the position for opening the frame and pulley, the spool, tension device, and reciprocating thread guide on the two part ring-pulley, and the lower half of the circularv frame and ring-pulley in the lowered or open position to receive the jack-spool, in broken lines. Fig. 4 is a detail sectional view taken on line X X of Fig. 3, showing the construction of the two-part circular frame and the two-part ring-pulley in the frame. Fig.

ring pulley, showing the spool of warpthread, the tension device, and the automatic reciprocating thread-guide on the two-part ring-pulley; and Fig. 6 is an enlarged detail sectional view taken on line X X of Fig. 3, showing the means for holding the two-part ring pulley from rotating in the circular frame when the frame and pulley are opened to receive the jack-spool.

In the drawings, (Z indicates the frame of the machine; Z) Z), the cross-struts; c, the supporting-frame; (Z. the driving-pulley; aspindle; f, a belt; g, a two-part circular frame; ZL, a two-part ring-pulley; Z, a belt; Z1, a spool; Z, a tension device; 711., an automatic thread-guide; 0, a jack-spool, and p a warp-thread.

The frame (4 consists of the four legs a a, the front rail (b the back rail a and the end rails (o a secured at their ends to the upper part of the legs to form a rectangular frame, as shown in Fig. 1. The cross-struts b b are secured at each end to the fittings Z b, which in turn are adjustably secured to the front and back rails by the set-bolts Z Z as shown in Fig. 2. The bearings Z Z)" each have a slot 6* for the shaft of the jack-spool and are adjustably secured to the cross-struts Z) Z) by a set-bolt Z), as shown in Fig. L. By this construction the cross-struts Z) I) are adjusted lengthwise on the front and back rails for different lengths of jack-spools and the jackspool adjusted on the struts for centering the same. The supporting-frame c is adjustably secured to the front rail (1 by the set-bolt 0 and has the upwardly-extending member 0 in which is the bearing 0 for the drivingpulley (Z and the bearing 0* for the spindle e. The arm 0" extends outward from the back of the frame 0 for rigidly supporting the fixed half of the two part circular frame g], as shown in Figs. 1 and 3. The front rail a extends through an opening in the frame 0, which approximately fits the rail.

The driving-pulley (Z has the handle cl. It is grooved for the belts f and t' and is rotatably secured to the bearing 0 by the shaftbolt (Z The spindle e is rotatably secured in the bearing 0* and has the grooved pulley c for the belt f, which connects the pulley c with the driving-pulley (Z, as shown in Fig. 3. A spool Zr? may be secured to the spindle c by friction or other well-known means.

The two-part circular frame consists of two semicircular segments, each segment forming one-half of a two-part circular ring. The fixed upper segment g has the arm 9 rigidly secured to the arm a" of the frame 0 by the bolts g the forked lugs g, and the screw-threaded transverse hole y for the thumb-screw g. The lower movable segment is pivotally secured at its lower end to the fixed segment 5 by the hinge g and has the lug g" on its upper end. The locking-bolt g is pivotally secured at one end to the lug g and has the thumb-nut g adapted to engage with the forked lug g on the upper fixed segment g and firmly hold the lower movable segment in the closed position, as shown in full lines in Fig. 3. Each segment forming the two-part circular frame g has the groove in its inner circumference, which when the two segments are secured together forms a continuous groove.

The two-part ring-pulley It consists of two semicircular segments it and if, each segment forming onehalf of a two-part ring, the break in the ring-pulley coinciding with the break in the circular frame 9. The segment Zt has the transverse hole Zr and the boss Zf supporting the pin Z1? on the side of the ringpulley. The spool 71;, filled with the warpthread j), is rotatably secured on the pin if by a spring-pressed point on the spool engaging with a groove in the end of the pin, as shown in broken lines in Fig. 5, or any other well-known means. Both segments of the ring-pulley have the lip Zr forming a continuous circular lip shaped to fit the circular groove in the frame g, and the \I-shaped circular groove Zt for the belt 71.

The tension device Z consists of the flat metal spring Z, secured to the side of the ringpulley [L by the screws Z The free end Z is in frictional contact with the end of the spool Z9, as shown in Fig. 5.

The automatic thread-guide m consists of the fiat metal guide-arm m, having the eyes m m in each end. This arm is pivotally secured adjacent one end to the bracket m" by the screw m and is limited in its movement by the stop an? on the bracket. The bracket m5 is rigidly secured to the side of the ringpulley ZL in a position to bring the longer end of the arm m adjacent the spool Zr. The warp-thread p is threaded from the spool Z: through the eyes of m in the arm m. As the thread unwinds from the spool it automatically reciprocates the guide-arm m, as shown in full and broken lines in Fig. 5, thus reciprocating the thread on the jack-spool to fill a cavity in the threads on the jack-spool, as indicated in broken lines in Fig. 1.

In the use of my improved jack-spool-filling machine a jack spool is filled with warpthreads from the creel in the usual way. After the jack-spool is filled it may be found that a thread is broken or an imperfect thread may have to be removed, leaving a cavity in the threads on the jack-spool to be filled by a perfect warp-thread. In the operation of my machine for this purpose the ring-pulley /2, is revolved until the break in the ring-pulley ZL coincides with the break in the circular frame g with the segment it at the top, when the thumb-screw g is screwed through the fixed segment 9 into the hole Zr in the ring-pulley, thus securing the segment Zt of the ringpulley to the fixed segment g of the circular frame g. The ring-pulley and circular frame are now opened to receive the jack-spool by removing the belt '27, unlocking the lockingbolt g and dropping the lower segments of the circular frame and ring-pulley into the position as shown in broken lines in Fig. 3. The jack-spool is now placed in the bearings If 6 on the cross-struts 7) b, the frame 9, with the ring-pulley it, closed and locked by the locking-bolt g", and the thumb-screw g removed from the hole it in the ring-pulley. An empty spool Z: is now placed on the spindle e and lilled with a warp-thread from a bobbin held by the operator by turning the drivingpulley (Z by the handle (Z. The lilled spool is now removed from the spindle a, placed on the pin it on the ring-pulley it, and the thread threaded through the thread-guide viz to the thread-cavity in the jack-spool. The supporting-frame c is now adjusted on the front rail (0 to bring the thread in the correct position on the jack-spool, the belt connecting the driving-pulley (Z with the ring-pulley replaced and the pulley (Z revolved by the handle (1 in the direction of the arrow, as shown in Fig. 3. This revolves the ring-pulley [L (through the belt vi) and the spool it, having the warp-thread around the jack-spool in the direction of the arrow on the ring-pulley. 'I'he warp-thread p is wound on the jack-spool and through the automatic thread-guide m is given a reciprocating motion on the jackspool and fills the cavity to the level of the adjacent threads.

It is evident that one of the cross-struts 66 could be dispensed with and a bearing I) adjustably secured to an end rail (0, if desired, without materially affecting the spirit of my invention.
